[Clinical features of KCNB1 gene variation related developmental and epileptic encephalopathy].

Objective: To summarize the clinical features of epilepsy and (or) developmental delay associated with KCNB1 gene variants in children. Methods: A case series study was conducted on 24 children with KCNB1 gene variants associated with epilepsy and (or) developmental delay who were treated at the Children's Medical Center of Peking University First Hospital and the Department of Neurology of Shenzhen Children's Hospital from July 2015 to June 2024. The manifestations of seizures, electroencephalogram (EEG) and genetic test results of those children were analyzed. Results: All the KCNB1 gene variants were de novo, involving 20 different variation, including 15 missense variations, 3 frameshift variations and 2 nonsense variations. There were 7 novel variations. Among the 24 developmental and epileptic encephalopathy children, there were 14 boys and 10 girls. The last follow-up age ranged from 9 months to 13 years and 9 months. Seizures were present in 21 children (88%), with onset ranging from 1 month to 7 years, and 76% (16/21) began before 2 years of age. The seizure types included focal seizures in 15 children (71%), epileptic spasms, myoclonic seizures, and generalized tonic-clonic seizures in 6 children respectively, atypical absence seizures in 4 children, and myoclonic atonic seizures in 1 child. Seventeen children (81%) had a cluster of seizures and 5 had a history of focal status epilepticus with impaired consciousness. All 24 children had varying degrees of developmental delay, with 3 presenting solely developmental delay. EEG abnormalities were present in all the 21 children with seizures, including focal or multifocal discharges in 20 children, generalized discharges in 10 children, hypsarrhythmia in 2 children, and electrical status epilepticus during sleep in 3 children. Magnetic resonance imaging abnormalities were found in 5 of the 24 children. Among the 21 children with seizures, 57% (12/21) achieved seizure control. Conclusions: KCNB1 gene variants are predominantly de novo missense variation. Most affected children present with epilepsy, though some may exhibit only developmental delay. Epilepsy often begins before 2 years of age, with focal seizures being the most common type. About 80% of patients experience clustered seizures. Although most patients achieve seizure control, they still exhibit varying degrees of developmental delay, consistent with developmental epileptic encephalopathy.

[A multicenter retrospective study on clinical features and pathogenic composition of septic shock in children].

Objective: To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China. Methods: Multi-center retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results: A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality (OR=1.04, 1.09, 0.67, 95%CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions: Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.

Blood transcriptomics reveal systemic eosinophilic and neutrophilic inflammation patterns in patients with nasal polyps.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic sinonasal disease characterized by heterogeneous inflammation. However, the presence of systemic inflammation heterogeneity in CRSwNP patients remains unknown. This study aims to profile transcriptomic alterations in the blood of CRSwNP patients and characterize the CRSwNP heterogeneity based on blood transcriptomic biomarkers. METHODOLOGY: Patients with CRSwNP were prospectively recruited from three hospitals and chronologically divided into exploratory (n=123) and independent validation (n=46) cohorts. Transcriptomic profiles were generated by whole blood mRNA sequencing and subjected to patient clustering, differential expression, and pathway analysis. Differences in immune pattern and clinicopathologic features between clusters were assessed. A transcriptomic signature was defined and applied to an independent cohort to validate the findings. RESULTS: CRSwNP patients showed diverse blood transcriptomic profiles versus healthy controls, or when stratified by tissue and blood eosinophils and asthma comorbidity. Transcriptome-wide correlation analysis revealed a transcriptional signature associated with blood eosinophil levels, consisting of nine T2-related genes (CLC, SIGLEC8, ALOX15, IL5RA, PTGDR2, CCL23, CCR3, EPX and IL1RL1). Three distinct clusters with differing systemic eosinophilic and neutrophilic inflammation patterns and asthma comorbidity were identified based on transcriptomic profiling of T2 and T1/3-related blood biomarkers. A 36-gene signature was developed by machine learning and accurately predicted the three CRSwNP subtypes. Validation on an independent cohort confirmed the prediction robustness. CONCLUSIONS: There is heterogeneous systemic inflammation associated with eosinophilic and neutrophilic patterns in patients with CRSwNP. Endotyping based on blood transcriptomic biomarkers might lead to more personalized treatment strategies for CRSwNP in the future.

[The 5-year relative survival rate among cancer patients in Henan province of China, 2015-2019].

Objective: To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data. Methods: Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019. Results: During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion: The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.

[Interpretation of the key points of Regulation for Diagnosis and Treatment of Non-neonatal Tetanus (2024 Edition)].

Non-neonatal tetanus is an acute, specific, toxic disease in patients over 28 days of age, characterized by continuous rigidity and paroxysmal spasms of the skeletal muscles throughout the body caused by the intrusion of Clostridium tetani through skin or mucosal membrane into the body and reproducing in anaerobic environments to produce exotoxins. The mortality rate of severe patients is close to 100% without medical intervention. Even with aggressive comprehensive treatment, the global mortality rate remains at 30%-50%, making it a potentially fatal disease. In order to standardize the diagnosis, treatment and prevention of non-neonatal tetanus, based on "Regulation for Diagnosis and Treatment of Non-Neonatal Tetanus (2019)", experts have revised this regulation according to clinical practice and recent research progress in this field to guide medical institutions in the prevention and control of non-neonatal tetanus. This article interprets the key points and basis for updating the 2024 edition regulation to guide clinical implementation and application.

Cerium doped yttrium aluminum perovskite scintillator as an absolute ultracold neutron detector.

The upcoming UCNProBe experiment at Los Alamos National Laboratory will measure the beta decay rate of free neutrons with different systematic uncertainties than previous beam-based neutron lifetime experiments. We have tested a new 10B-coated Yttrium Aluminum Perovskite (YAP:Ce) scintillator and present its properties. The advantages of the YAP:Ce scintillator include its high Fermi potential, which reduces the probability for upscattering of ultracold neutrons (UCN), and its short decay time, which increases sensitivity at high counting rates. Birks' coefficient of YAP:Ce was measured to be (5.56-0.30+0.05)×10-4 cm/MeV. The loss of light due to the 120 nm 10B-coating was measured to be about 60%, and the loss of light from YAP:Ce due to transmission through a deuterated polystyrene scintillator was about 50%. The efficiency for neutron capture on the 10B coating was (86.8 ± 2.6)%, and a measurement using UCN showed that the YAP:Ce crystal counted 8%-28% more UCN compared to a ZnS:Ag screen. The difference may be due to the uneven coating of 10B on the rough surface of ZnS:Ag.

[Progress in health-related quality of life in patients with pulmonary hypertension].

Pulmonary hypertension is a disease that impairs cardiopulmonary function and is characterised by the limitation of progressive physical activity and decline in health-related quality of life. Patients usually present with a range of severe symptoms, including dyspnoea, fatigue, chest pain and oedema, which affect their quality of life. Compared to the general population, patients usually have a lower health-related quality of life, with differences in several aspects such as physical functioning, mental health, social interactions and career. The aim of this review is to examine recent research advances in health-related quality of life in patients with pulmonary hypertension, including its influencing factors and improvement measures, in order to improve the understanding and management of this condition.

Probiotics/prebiotics/synbiotics and human neuropsychiatric outcomes: an umbrella review.

The neuropsychiatric effects of probiotics, prebiotics, and synbiotics have been gaining attention since the rise of microbial-gut-brain axis research. Nevertheless, some of the findings are inconsistent, and few studies have analysed the similarities and differences in the neuropsychiatric effects of the three comprehensively. To reveal the respective neuropsychiatric effects of probiotics, prebiotics, and synbiotics and synthesise the similarities and differences among the three effects, 47 meta-analyses with 12 types of neuropsychiatric results were integrated under an umbrella review. Probiotics, prebiotics, and synbiotics intake might all be associated with improvements in some neuropsychiatric outcomes, including neuropsychological test outcomes (probiotic and prebiotic), hepatic encephalopathy outcomes (probiotic, prebiotic, and synbiotic), instant memory in patients with Alzheimer's disease (probiotic), depressive symptoms (probiotic, prebiotic and synbiotic), mood states and psychiatric distress (probiotic), overall mental health (probiotic), neurological function (probiotic), brain-derived neurotrophic factor (BDNF) concentration (probiotic and synbiotic), and Pittsburgh Sleep Quality Index (PSQI) score (probiotic). All three are similar in that the intake of probiotics, prebiotics, and synbiotics might be associated with improvements in hepatic encephalopathy outcomes and depressive symptoms, both probiotic and synbiotic intake might be associated with elevated BDNF concentrations, and both probiotic and prebiotic intake might be associated with improved neuropsychological test results. The difference between the three is that the neuropsychiatric effects of probiotics might be more widespread and be reflected in the fact that probiotic intake might also be associated with improvements in mood states and psychiatric distress, overall mental health, neurological function, Alzheimer's disease patients' instant memory, and PSQI score. Probiotics might be the best and most promising option for improving neuropsychiatric outcomes. In the future, in addition to requiring more high-quality meta-analyses, further preclinical studies are needed to explore specific relevant mechanisms and determine true causal relationships.

Intermanufacturer assessment of diagnostic performance of angiogenic ratio vs glycosylated fibronectin in women with suspected pre-eclampsia.

OBJECTIVE: To compare the diagnostic performance of different manufacturers' immunoassays for the soluble fms-like tyrosine kinase-1 (sFlt-1)-to-placental growth factor (PlGF) ratio with that of a point-of-care test for glycosylated fibronectin (GlyFn) in women with suspected pre-eclampsia (PE). METHODS: This was a prospective, single-center, double-blinded, non-interventional study of East Asian women with a singleton pregnancy who presented with hypertension with or without clinical features of PE after 20 weeks' gestation between January 2020 and March 2022. Maternal serum samples were collected at the time of presentation, and subsequent management followed the departmental protocol, based on gestational age, severity of hypertension, fetal condition and presence of severe PE features. Women diagnosed with PE at presentation were excluded. PE was diagnosed according to the 2018 International Society for the Study of Hypertension in Pregnancy classification. Levels of sFlt-1 and PlGF were measured using the Cobas e411 (Roche Diagnostics), BRAHMS KRYPTOR (ThermoFisher Scientific) and iMAGIN 1800 (Ningbo-Aucheer) platforms. GlyFn levels were measured using the Lumella™ GlyFn PoC test (Diabetomics). The predictive performance of each test to rule out PE within 7 days and rule in PE within 28 days from the date of presentation was assessed. Based on the PROGNOSIS study, a sFlt-1/PlGF ratio of ≤ 38 on the Roche platform was used to predict the absence of PE within 7 days. The sFlt-1/PlGF ratio was classified as high or low using platform-specific thresholds equivalent to a Roche sFlt-1/PlGF ratio of 38, which were derived using Passing-Bablok regression. GlyFn was categorized as high or low using two reported clinical management thresholds (263 µg/mL and 510 µg/mL). RESULTS: Overall, 236 women with suspected PE were included, of whom 70 (29.7%) were diagnosed with PE; 36 (51.4%) and 70 (100%) developed PE within 7 days and 28 days, respectively. Eighty-eight (37.3%) women had a sFlt-1/PlGF ratio of > 38 on the Roche platform, 79 (33.5%) women had a sFlt-1/PlGF ratio of > 55 on the KRYPTOR platform and 96 (40.7%) women had a sFlt-1/PlGF ratio of > 40 on the iMAGIN 1800 platform. Furthermore, 62 (26.3%) and four (1.7%) women had a GlyFn level of > 263 µg/mL and > 510 µg/mL, respectively. The negative predictive value (NPV) of the sFlt-1/PlGF ratio measured on the Roche, KRYPTOR and iMAGIN 1800 platforms to rule out PE within 7 days after presentation was 83.3%, 82.0% and 82.9%, respectively, while that for GlyFn > 263 µg/mL and > 510 µg/mL was 82.6% and 70.4%, respectively. The corresponding positive predictive values (PPV) to rule in PE within 28 days after presentation were 50.5%, 52.3% and 46.7%, respectively, for the sFlt-1/PlGF ratio, and 35.4% and 50.0%, respectively, for GlyFn > 263 µg/mL and > 510 µg/mL. CONCLUSIONS: The predictive performance of different manufacturers' assays for the sFlt-1/PlGF ratio to rule in and rule out PE were similar once standardized to a common threshold. Our findings suggest that the sFlt-1/PlGF ratio and GlyFn using a cut-off of 263 µg/mL can both be utilized to rule out PE within 7 days after assessment, with a moderate NPV. The PPV for ruling in PE within 28 days remains poor. © 2024 The Author(s).

Structural Transformation of Metastable Two-Electron Superatom Au-Doped Cu-Rich Alloy Nanocluster.

The ability to fabricate bimetallic clusters with atomic precision offers promising prospects for elucidating the correlations between their structures and properties. Nevertheless, achieving precise control at the atomic level in the production of clusters, including the quantity of dopant, characteristic of ligands, charge state of precursors, and structural transformation, have remained a challenge. Herein, we report the synthesis, purification, and characterization of a new bimetallic hydride cluster, [AuCu11(H){S2P(OiPr)2}6(C≡CPh)3] (AuCu11H). The hydride position in AuCu11H was determined using DFT calculations. AuCu11H comprises a ligand-stabilized defective fcc Au@Cu11 cuboctahedron. AuCu11H is metastable and undergoes a spontaneous transformation through ligand exchange into the isostructural [AuCu11(Cl){S2P(OiPr)2}6(C≡CPh)3] (AuCu11Cl) and into the complete cuboctahedral [AuCu12{S2P(OiPr)2}6(C≡CPh)4]+ (AuCu12) through an increase in nuclearity. These structural transformations were tracked by NMR and mass spectrometry.

Safety and clinical activity of BMS-986365 (CC-94676), a dual androgen receptor ligand-directed degrader and antagonist, in heavily pretreated patients with metastatic castration-resistant prostate cancer.

BACKGROUND: Metastatic castration-resistant prostate cancer (mCRPC) that progresses on androgen receptor pathway inhibitors (ARPIs) may continue to be driven by AR signaling. BMS-986365 is an orally administered ligand-directed degrader targeting the AR via a first-in-class dual mechanism of AR degradation and antagonism. CC-94676-PCA-001 (NCT04428788) is a phase I multicenter study of BMS-986365 in patients with progressive mCRPC. PATIENTS AND METHODS: Patients who progressed on androgen deprivation therapy, one or more ARPIs, and taxane chemotherapy (unless declined/ineligible) were enrolled. The study included dose escalation (part A) and expansion (part B) of BMS-986365 up to 900 mg twice daily. Primary objectives were safety and tolerability, and to define maximum tolerated dose and/or recommended phase II dose. Key secondary endpoints included decline in prostate-specific antigen ≥50% (PSA50) and radiographic progression-free survival (rPFS). RESULTS: Parts A and B enrolled 27 and 68 patients, respectively. In part B, the median number of prior therapies was 4 (range 2-11). The most common treatment-related adverse events were asymptomatic prolonged corrected QT interval (47%) and bradycardia (34%). Part A maximum tolerated dose was not reached and recommended phase II dose selection is ongoing. Across part B three highest doses (400-900 mg twice daily, n = 60), PSA50 was 32% (n = 19), including 50% (n = 10/20) at 900 mg; median rPFS (95% confidence interval) was 6.3 months (5.3-12.6 months), including 8.3 months (3.8-16.6 months) at 900 mg; and rPFS was longer in patients without versus with prior chemotherapy: 16.5 months (5.5 months-not evaluable) versus 5.5 months (2.7-8.3 months), respectively. Efficacy was observed in patients with mCRPC with AR ligand binding domain (LBD) WT or with AR LBD mutations. CONCLUSIONS: BMS-986365 was well tolerated, with a manageable safety profile, and demonstrated activity in heavily pretreated patients with mCRPC with potentially higher benefit in chemotherapy-naive patients. These data show the potential of BMS-986365 to overcome resistance to current ARPIs, regardless of AR LBD mutation status.

[Clinical characteristics analysis of persistent airflow limitation in asthmatic children].

Objective: To analyze the clinical characteristics of asthmatic children with persistent airflow limitation (PAL) in order to improve understanding of PAL and improve asthma management. Methods: The clinic data of asthmatic children aged 6 to 18 years with and without PAL, who visited the Department of Allergy at Children's Hospital of the Capital Institute of Pediatrics between January 2021 and June 2023, were analyzed retrospectively. The study included a total of 197 patients (153 males and 44 females), with a median age of 9.0 (7.0, 12.0) years. The analysis encompassed demographic features, disease-related factors, laboratory tests, and spirometry parameters. Quantitative data differences between the two groups were assessed using the Student's t-test or the Mann-Whitney U test. Qualitative data comparisons were made using the Chi-square test or Fisher's exact test. Results: This study included 100 non-PAL and 97 PAL patients. The female-to-male ratio in the two groups was 27/73 and 17/80, respectively. Age and BMI were 11.0 (10.0, 13.0) years and 20.3 (17.7, 24.1) kg/m2 in the PAL group, which was significantly higher than in the non-PAL group (P<0.001). Among the PAL group, 49.5% fell within the 9-12 age group. The PAL group had a higher percentage of patients with an asthma duration of more than 3 years (89.7% vs. 62.0%, P<0.001) and a history of pneumonia (13.4% vs. 4.0%, P=0.036) compared to the non-PAL group. Regarding laboratory tests, a higher percentage of patients in the PAL group had an elevated FeNO level (60.9% vs. 37.6%, P=0.002) and animal sensitization (50.7% vs. 30.7%, P=0.022) compared to the non-PAL group. Of the 69 patients who underwent spirometry before and after PAL development, FEV1%pred, FEV1/FVC, and MMEF%pred values gradually decreased, with a significant decline in the year preceding PAL development. Conclusions: Asthmatic children with PAL had characteristics such as relatively older age, higher BMI, longer duration of asthma, eosinophilic inflammation, and atopy. Lung function decline occurred several years before PAL development. Long-term follow-up should focus on the evolving trend of spirometry parameters.

Controlled aggregation of Pt/PtH/Rh/RhH doped silver superatomic nanoclusters into 16-electron supermolecules.

The assembly of discrete superatomic nanoclusters into larger constructs is a significant stride towards developing a new set of artificial/pseudo-elements. Herein, we describe a novel series of 16-electron supermolecules derived from the combination of discrete 8-electron superatomic synthons containing interstitial hydrides as vertex-sharing building blocks. The symmetric (RhH)2Ag33[S2P(OPr)2]17 (1) and asymmetric PtHPtAg32[S2P(OPr)2]17 (2) are characterized by ESI-MS, SCXRD, NMR, UV-vis absorption spectra, electrochemical and computational methods. Cluster 1 represents the first group 9-doped 16-electron supermolecule, composed of two icosahedral (RhH)@Ag12 8-electron superatoms sharing a silver vertex. Cluster 2 results from the assembly of two distinct icosahedral units, Pt@Ag12, and (PtH)@Ag12. In both cases, the presence of the interstitial hydrides is unprecedented. The stability of the supermolecules is investigated, and 2 spontaneously transforms into Pt2Ag33[S2P(OPr)2]17 (3) with thermal treatment. The lability of the hydride within the icosahedral framework in solution at low-temperature was confirmed by the VT-NMR.

The mediating effect of lifestyle behaviors on the relationship between self-perceived work stress and suboptimal health status: a cross-sectional study involving Chinese urban workers.

STUDY DESIGN: Cross-sectional study. OBJECTIVES: Suboptimal health status (SHS) is a third state between health and disease. Long-term being SHS will be detrimental to one's ability development. Previous studies have demonstrated the associations of lifestyle behaviors or work stress with SHS, but few studies have comprehensively analyzed the underlying factors and mechanisms between the three. This study aimed to investigate whether lifestyle behaviors mediated the relationship between self-perceived work stress and SHS. METHODS: A total of 4238 urban workers, who participated in a cross-sectional survey conducted from December 2018 to October 2019, were included. A general linear model was used to explore the associations between lifestyle behaviors and self-perceived work stress with SHS after adjusting for demographic variables. Structural equation modeling was performed to examine the mediation by lifestyle behaviors. RESULTS: The mean transformed scores of physical, mental, and social SHS were 70.98, 67.17, and 61.72, respectively. Unhealthy lifestyle behaviors and high self-perceived work stress positively affected SHS (P < 0.001). Self-perceived work stress imposed negative effects on physical SHS (ß = -0.228, P < 0.001), mental SHS (ß = -0.237, P < 0.001), and social SHS (ß = -0.092, P < 0.001). The indirect effects of self-perceived work stress on physical SHS (ß = -0.139, 95% CI: -0.178 to -0.106), mental SHS (ß = -0.106, 95% CI: -0.134 to -0.082), and social SHS (ß = -0.121, 95% CI: -0.154 to -0.092) were statistically significant. CONCLUSIONS: Lifestyle behaviors and self-perceived work stress were significantly associated with SHS among Chinese urban workers. The mediating effects of unhealthy lifestyle behaviors were found in the relationship between high self-perceived work stress and SHS. Future longitudinal research may verify these associations and elucidate the underlying mechanisms.

[Qingshen Granules alleviates renal fibrosis in mice by regulating exosomes, miR-330-3p, and CREBBP expression].

OBJECTIVE: To explore the effects of Qingshen Granules (QSG) on adenine-induced renal fibrosis in mice and in uric acid (UA)-stimulated NRK-49F cells and its mechanism for regulating exosomes, miR-330-3p and CREBBP. METHODS: A mouse model of adenine-induced renal fibrosis were treated daily with QSG at 8.0 g·kg-1·d-1 via gavage for 12 weeks. An adenoassociated virus vector was injected into the tail vein, and renal tissues of the mice were collected for analyzing exosomal marker proteins CD9, Hsp70, and TSG101 and expressions of Col-III, α-SMA, FN, and E-cad using Western blotting and immunofluorescence and for observing pathological changes using HE and Masson staining. In the cell experiment, NRK-49F cells were stimulated with uric acid (400 µmol/L) followed by treatment with QSG-medicated serum from SD rats, and the changes in expressions of the exosomal markers and Col-III, α-SMA, FN, and E-cad were analyzed. Dual luciferase reporter assay was employed to examine the targeting relationship between miR-330-3p and CREBBP, whose expressions were detected by RT-qPCR and Western blotting in treated NRK-49F cells. RESULTS: The mouse models of adenine-induced renal fibrosis showed significantly increased levels of CD9, Hsp70, and TSG101, which were decreased by treatment with QSG. The expressions of Col-III, α-SMA, and FN increased and Ecad decreased in the mouse models but these changes were reversed by QSG treatment. QSG treatment obviously alleviated renal fibrosis in the mouse models. Intravenous injection of adeno-associated viral vector obviously inhibited miR-330-3p, increased CREBBP levels, and reduced fibrosis in the mouse models. Dual luciferase assay confirmed CREBBP as a target of miR-330-3p, which was consistent with the results of the cell experiments. CONCLUSION: QSG inhibits renal fibrosis in mice by regulating the exosomes, reducing miR-330-3p levels, and increasing CREBBP expression.

[Experts consensus on standard items of the cohort construction and quality control of temporomandibular joint diseases (2024)].

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients'suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

What can we learn from the experiment of electrostatic conveyor belt for excitons?

Motivated by the experiment of electrostatic conveyor belt for indirect excitons (Winbowet al2011Phys. Rev. Lett.106196806), we studied the exciton patterns for understanding the exciton dynamics. By analyzing the exciton diffusion, we found that the patterns mainly came from the photoluminescence of two kinds of excitons. The patterns near the laser spot came from the hot excitons which can be regarded as the classical particles. However, the patterns far from the laser spot come from the cooled or coherent excitons. Considering the finite lifetime of Bosonic excitons and of the interactions between them, we built a time-dependent nonlinear Schrödinger equation including the non-Hermitian dissipation to describe the coherent exciton dynamics. The real-time and imaginary-time evolutions were used alternately to solve the Schrödinger equation to simulate the exciton diffusion accompanied by the exciton cooling in the moving lattices. By calculating the escape probability, we obtained the transport distances of the coherent excitons in the conveyor, consistent with the experimental data. The cooling speed of excitons was found to be important in coherent exciton transport. Moreover, the plateau in the average transport distance cannot be explained by the dynamical localization-delocalization transition induced by the disorders.
